Pulse control module for time proportional output

Omega Engineering's PCM5 is designed to transmit a signal of up to 20 mA from a process/temperature controller to a time proportional output.


The OMEGA PCM5 Series converter is designed to convert a 4 to 20 mA signal from a process/temperature controller or computer to a time proportional output.

The modules mount directly to the input terminals on a 3 to 32 Vdc input SSR, and supports single phase 50 or 60 Hz operation. Lever clamps are provided on the converter for the 4 to 20 mA input.

The SSR’s power section provides easy connection to the line and load.


Analog Input Signal: 4 to 20 mA minimal; 0 to 30 mA permissible; reverse polarity protected; no abnormal operation below 4 mA Compliance Voltage Requirement: 6.4V

Time Base: ~200 mS @ 50%, ~500 mS towards 0 and 100%

Ambient Temperature: 0 to 40°C (32 to 104°F)


Dimensions: 45 L x 51 W x (1.75 x 2.0 x 0.80") 20 mm D
