The OMEGA™ PCM series converter
modules facilitate conversion of a
4 to 20 mA output to an on/off time
proportioning output. The modules
mount directly to the input terminals
of an SSR. Screw terminals are
provided on the converter of the
4 to 20 mA control signal. The
SSR’s power section connects in
standard fashion to the line
and load.
The PCM module with a solid state
relay provides a rectangular shape,
time proportional (zero-fired) control
signal to the load. Thus, the average
power to the load is proportional to
the 4 to 20 mA input signal.
SPECIFICATIONS Analog Input Signal: 4 to 20 mAdc Note: Control signal cannot drop below 4 mAdc or improper operation may occur. Compliance Voltage Requirement: Time Base: 3 cycle resolution 6.4 Vdc (320 Ω @ 20mA) Ambient Temperature: 0 to 40°C (32 to 104°F) Dimensions: 32 W x 45 L x 20 mmD (1.25 x 1.75 x 0.75")
