Channel-to-Channel Isolation & DCS Interconnection
The 900H02-0202 module delivers 16 channels of solid-state 24 VDC output signals to drive external relays, solenoids, and indicator panels. Integrated optical isolation shields the internal HC900 system backplane bus from external field transients up to 1500 V RMS. Operating alongside 4-20 mA HART loop protocol analog cards in the controller rack, the 16-point digital card maintains strict signal integrity and low cross-talk interference across adjacent field channels.
Frequently Asked Questions
Q: Does the 900H02-0202 digital output module support sink or source wiring configurations?
A: The module is designed specifically for 24 VDC current-sourcing outputs, providing positive voltage directly to connected field loads.
Q: What is the channel isolation level between the field wiring terminals and backplane logic?
A: Field circuitry is galvanically isolated from backplane logic at up to 1500 V RMS via internal optical coupling.
Field Installation Guidelines
- Turn off main power to the backplane rack and field power supplies before inserting or removing the module.
- Route 24 VDC digital output wiring in separate wiring ducts away from high-voltage AC lines to prevent capacitive coupling and electrical noise.
- Use external flyback diodes across inductive field loads (such as DC solenoid coils and relay coils) to suppress voltage spikes during channel turn-off.
- Ensure field power supply connections comply with the 20-30 VDC operational range and tighten terminal block screws to manufacturer torque specifications.
