Flexem PLC Comparison: FR-D0016P Module & FC5 Series
Flexem FR-D0016P & FC5 Series PLCs: Your Guide to Digital Output and Compact Control
Choosing the right automation components is critical for building efficient and reliable systems. For industrial control that demands high-current switching or versatile programmable logic, Flexem offers robust solutions. This guide explores the FR-D0016P digital output module and the flexible FC5 Series of micro-PLCs. We’ll compare their functions to help you select the best fit for your application.
Understanding Core Functions and Operating Principles
The FR-D0016P and FC5 Series PLCs serve distinct but complementary roles on the factory floor. Understanding their core purpose is the first step in selection.
- ✅ Flexem FR-D0016P – Digital Output Module: This is a specialized output expansion module. It acts as a high-power switch, receiving low-voltage control signals (e.g., 24V DC) from a central PLC and using internal relays to switch high-current AC or DC loads (up to 2A per point). Its primary role is to interface and amplify control signals to actuate devices like solenoids, contactors, motor starters, and indicator lamps. It requires a master controller (like a PLC) to operate.
- ✅ Flexem FC5 Series – Micro Programmable Logic Controller (PLC): These are complete, compact control brains. A PLC like the FC5-30MR-AC contains a microprocessor, memory, power supply, and integrated Input/Output (I/O) points. It executes a user-written control program to read inputs (sensors, switches), make logic decisions, and command outputs (like an FR-D0016P or its own built-in outputs). The “MR” designation indicates it has integrated relay outputs for direct device control.
Key Technical Specifications and Comparison
Selecting between a standalone output module and a full PLC depends on your system’s existing architecture and I/O needs. The table below summarizes the key differences:
| Feature | Flexem FR-D0016P | Flexem FC5 Series PLC (e.g., FC5-30MR-AC) |
|---|---|---|
| Primary Function | High-current relay output expansion | Complete programmable logic controller |
| I/O Points | 16 outputs only (Relay) | Combined I/O (e.g., 30 pts: Inputs + Relay Outputs) |
| Control Logic | None (requires external PLC) | Built-in (user-programmable) |
| Communication | Via master controller’s network | Built-in Ethernet & Serial ports |
| Typical Use Case | Adding output capacity to an existing PLC system | Standalone control of a small to medium machine |
Author’s Insight from PLCDCSHUB: The choice often comes down to scale. For a new machine line, start with a capable FC5 PLC. If your main PLC has run out of outputs while adding equipment, the FR-D0016P is a perfect, cost-effective expander.
Choosing Within the FC5 Series: AC vs. DC and I/O Count
The FC5 Series offers models tailored to different power environments and complexity levels. Here’s how to choose:
- 🔧 Power Supply (AC vs. DC): Models like the FC5-30MR-AC use a wide-range AC power supply (e.g., 100-240V AC), common in panel boxes. The FC5-30MR-DC runs on 24V DC, typical in environments with centralized DC UPS systems or for reduced electrical noise.
- 🔧 I/O Point Capacity: The number dictates the machine’s complexity you can control.
- FC5-20MR-AC (20 I/O): Ideal for simple machines (e.g., conveyor starter, small press).
- FC5-30MR-AC/DC (30 I/O): The most versatile balance for mid-range applications (e.g., packaging machine, palletizer).
- FC5-40MR-AC (40 I/O): Suited for more complex processes with many sensors and actuators.
- 🔧 Communication Needs: All FC5 models feature built-in Ethernet for programming, HMI connectivity, and basic data exchange. This is essential for modern, connected industrial setups.
Practical Application Scenarios
These components solve specific automation challenges. Here are two common scenarios:
Scenario 1: Upgrading an Aging Control Panel
A control panel for a industrial oven uses an old relay logic system that is unreliable. You need automated temperature staging and safety interlocks.
Solution: Replace the relay maze with a FC5-30MR-AC PLC. It reads temperature controllers and door sensors, executes the timing logic, and directly controls heating contactors and fan motors via its relay outputs. The Ethernet port allows for recipe download from an HMI.
Scenario 2: Expanding a Conveyor Line
An existing packaging line controlled by a main PLC needs two new diverting stations. The main PLC has no spare outputs.
Solution: Add an FR-D0016P output module to the system. The main PLC sends commands over the network, and the FR-D0016P uses its high-current relays to power the solenoids for the new diverting arms, seamlessly extending the line’s capability.
Frequently Asked Questions (FAQ)
- Q: Can I connect an FR-D0016P module directly to a Flexem FC5 PLC?
A: Yes, absolutely. The FC5 PLC can be the master controller. You would connect the FR-D0016P to the FC5’s expansion bus or via a network (depending on the specific communication interface of the FR-D0016P), allowing the FC5 to command its 16 high-power outputs. - Q: What is the main advantage of relay outputs (the “R” in MR) on these units?
A: Relay outputs are voltage-agnostic and can switch both AC and DC loads. They provide physical isolation between the sensitive PLC electronics and the potentially noisy load circuit. This makes them robust and versatile for driving a wide array of industrial devices. - Q: For a new small machine, should I buy a larger PLC or a smaller PLC with expansion modules like the FR-D0016P?
A: For simplicity and cost-effectiveness in small machines, choose a single FC5 PLC with enough built-in I/O points (with 20-30% spare for future changes). Expansion modules add cost and complexity. Use them when you exceed the capacity of the largest cost-effective standalone PLC or when adding to an existing system.
