PLC-5 Relay Output Electrical Characteristics
The 1771-OW16/B uses mechanical relay contacts to provide channel-to-channel electrical isolation for discrete output switching. The relay architecture allows AC and DC field circuits to be controlled from the PLC-5 I/O chassis without solid-state leakage current. Each output channel operates independently for mixed field device connection, including solenoids, pilot lights, and motor starter control circuits.
For Allen-Bradley PLC-5 systems, the module integrates through the rack backplane interface. The I/O density scaling of the 1771 family allows multiple relay output modules to be configured within a chassis according to available slot allocation and backplane loading requirements. Firmware flash compatibility is not applicable to this relay output hardware.
Frequently Asked Questions
Q: Does the 1771-OW16/B support both AC and DC field loads?
A: Yes. The relay contact outputs support AC loads from 5 to 240 VAC and DC loads from 5 to 125 VDC within the specified current ratings.
Q: Does the module generate output leakage current when switched off?
A: No. Mechanical relay contacts provide physical isolation and do not create solid-state off-state leakage current.
Q: What type of field wiring connection is required?
A: The module uses the 1771-WH wiring arm for field terminal connection and installation within a compatible 1771 I/O chassis.
Field Installation Guidelines
Install the 1771-OW16/B module in a compatible Allen-Bradley 1771 I/O chassis with the correct keying position and rack configuration. Verify backplane power availability before installation.
Route relay output wiring separately from low-level analog signal wiring to reduce electrical interference. Use appropriate field wiring practices for AC and DC circuits, including protective grounding and terminal tightening according to installation requirements. Confirm load voltage, current rating, and contact configuration before connecting field devices.
