5 Professional FAQs (New Questions)
Q1: Can I use this module in an Innovation Series drive?
Yes. The IS215ACLEH1A works in Innovation Series drives. However, it does NOT replace the older ACLA module for that series. Check your system manual first.
Q2: What is the difference between IS215ACLEH1 and IS215ACLEH1A?
The H1A is the A-rated functional revision. It came after the base H1 model. A-rated means minor improvements. Both work similarly. For new purchases, choose H1A.
Q3: How do I download runtime code to this module?
Use the Toolbox software. Connect through ENET1 Ethernet port. The download happens over the network. Do not use serial ports for this task.
Q4: What happens if both CPU and DSPX access the same DPRAM address?
The hardware solves this automatically. It delays one board for up to 100 ns. You do not need to do anything. The system keeps working normally.
Q5: How fast is delivery?
We ship within 24 hours after payment. For example, choose FedEx Priority (2-5 days), UPS Worldwide Express, or DHL Express Easy. Additionally, all options include tracking numbers.
Selection Guide (Buying Help)
Use this checklist to pick the right EX2100 control module for your job.
Application type : For excitation control, choose ACLE. For other tasks, choose different EX2100 boards.
Rack type : Check if your rack has IS200ESBP, EBKP, ERBP, or ERRB backplane.
Processor speed : This model has 100 MHz. Newer versions have 266 or 400 MHz.
Ethernet needed : This model gives two ports. One is 10BaseT. The second supports 10/100 Mbps.
Serial ports needed : Two RS-232 ports (COM1 and COM2) are included.
Pro tip : For faster processing, look for IS215ACLEH1A boards with Pentium CPU. For basic tasks, the 486 at 100 MHz works fine. Always check your existing system’s requirements before buying.
