Backplane Bus Communication Velocity and System Integration

The IC693ALG391 converts 12-bit digital output data from the CPU memory table into analog voltage or current drive signals across 2 independent channels. High-speed backplane bus communication velocity allows updated digital counts to be processed into physical field outputs within a 5 ms channel update cycle.

Firmware flash compatibility across Series 90-30 baseplate configurations supports installation in any standard 5-slot or 10-slot baseplate. The module incorporates 1500 VAC field-to-logic galvanic isolation to suppress ground loops and maintain deterministic execution across high-density I/O configurations.

Frequently Asked Questions

Q: What are the dual backplane power supply requirements for operating the IC693ALG391?

A: The module draws 30 mA from the +5 VDC backplane supply and 215 mA from the isolated +24 VDC backplane bus or an external 20 to 30 VDC user supply.

Q: What level of electrical isolation exists between the field terminal wiring and system logic?

A: The field-to-logic side circuits are isolated to withstand up to 1500 VAC for a duration of 1 minute.

Q: What resolution values correspond to 1 LSB in the 4 to 20 mA and 0 to 5 VDC operating modes?

A: In 4 to 20 mA mode, 1 LSB equals 4 uA; in 0 to 5 VDC mode, 1 LSB equals 1.25 mV.

Field Installation Guidelines

Ensure baseplate power is completely isolated before inserting or removing the module from the chassis slot.
Wire current loop and voltage field output devices using twisted, shielded conductors to minimize external high-frequency noise.
Connect the cable shield to a single earth point near the panel entry to prevent circulating ground currents.
Verify that the external loop power supply falls strictly within the specified 20 to 30 VDC limits when not using isolated backplane 24 VDC power.
