Backplane Bus Communication Velocity & I/O Density Scaling
The IC670MDL240J expands I/O density scaling by integrating 16 isolated AC input points within a compact DIN-rail footprint. Channel opto-isolation circuitry segregates high-voltage AC field transients from internal system logic, preventing electrical noise transmission to the host backplane. This arrangement preserves deterministic backplane bus communication velocity across local expansion racks while maintaining firmware flash compatibility with target PACSystems RX3i and Series 90-30 controllers over the Bus Interface Unit bridge.
Frequently Asked Questions
Q: How is field power isolated across the channels on the IC670MDL240J?
A: The module splits 16 input channels into two distinct groups of 8 points, allowing each bank to run on an independent external 120 VAC power source for complete phase or group isolation.
Q: What current draw does the IC670MDL240J place on the backplane logic supply?
A: The module draws a maximum of 77 mA directly from the 5 VDC logic supply provided by the local Bus Interface Unit.
Q: What cable sizes does the removable terminal assembly accept?
A: The removable screw or barrier terminal block accommodates field wiring gauges from AWG #14 down to AWG #22.
Field Installation Guidelines
- Isolate all field voltage sources and de-energize the Bus Interface Unit before inserting or replacing the module assembly.
- Connect independent 120 VAC power supplies to group 1 (points 1-8) and group 2 (points 9-16) when inter-group electrical isolation is required.
- Secure field wiring into the removable terminal block using AWG #14 to #22 conductors, ensuring terminal screws are torqued to specification.
- Separate 120 VAC discrete signal cabling from sensitive DC communication wires to mitigate inductive voltage coupling.
- Check front-panel LED indicators during commissioning to verify power delivery and channel logic status.
