Backplane Bus Communication Velocity & I/O Density Scaling
The IC693MDL241 input module updates discrete channel data into the CPU %I logic memory map across the backplane bus within a 12 ms On-response and 28 ms Off-response delay. Optimized for backplane bus communication velocity and I/O density scaling, the 16-point single-group topology supports positive or negative logic in DC mode, as well as 50/60 Hz AC signals. Logic-side circuits draw 80 mA from the 5 VDC backplane bus when all channels are active, while field power consumes 125 mA from the isolated 24 VDC bus or a user-provided power supply. Galvanic isolation of 1500 V RMS protects the internal backplane logic from external field circuit spikes.
Frequently Asked Questions
Q: What power sources can be used to supply the input field circuits on the IC693MDL241?
A: Field circuits can be powered using an external 24 VAC/VDC user supply or the isolated 24 VDC output supplied directly by the baseplate power supply.
Q: What are the logic threshold limits for detecting On and Off channel states?
A: The module registers an On-state at 11.5 to 30.0 VAC/VDC (3.2 mA minimum) and an Off-state at 0 to 4 VAC/VDC (1 mA maximum off-state current).
Q: What are the backplane current draw requirements for this 16-point input module?
A: The module consumes 80 mA from the 5 VDC backplane bus when all 16 inputs are ON, plus 125 mA from the isolated 24 VDC backplane supply or external user source.
Field Installation Guidelines
- Remove primary power from the Series 90-30 baseplate and field power distribution loops before inserting or servicing the module.
- Align the module chassis with the target slot on a 5-slot or 10-slot Series 90-30 baseplate and push until the backplane connector engages fully.
- Tighten the top panel mounting screw to secure mechanical holding and establish solid chassis earth grounding.
- Route field contact wiring (limit switches, pushbuttons, proximity sensors) to the terminal block, ensuring AC or DC voltage levels stay within the 0 to 30 V range.
- Separate low-voltage input conductors from high-voltage AC lines to minimize noise coupling, grounding all cable shielding at a single frame terminal.
