Model Explanation

1C31: Prefix for the Ovation IO series; 232: 8-channel differential DI; G02: Hardware revision version. Technical Specifications

Power Supply: Back panel 5V + On-site side 24VDC;

Channels: 8 differential isolated inputs; Input signals: Passive dry contacts, differential small voltage signals;

Isolation: Channel-to-back panel 1500VAC isolation;

Operating temperature: -40℃ to +70℃; Total power consumption ≈ 3W;

Interface and communication configuration

European-style plug on the rear connects to the Ovation rack back panel; Terminal block on the front connects to the on-site switch cable; Panel RUN, FAULT, and channel position indicator lights. Core function

Differential circuit anti-interference against frequency conversion; hardware self-diagnosis for open circuit / short circuit; fault transmission to the system; single-channel faults do not interfere with each other; supports hot plugging of the rack while powered on. Applicable scenarios

Boiler FSSS and turbine TSI switch acquisition, chemical Ovation unit interlock DI cabinet.

Operation and maintenance instructions

Shielded single-ended cabinet of signal cables is grounded; separate layers are used for power cables; unused terminals are left hanging or short-circuited for protection.
