The Crydom MCPC series of Proportional Control Relays
incorporate a complete phase-fired logic system and Solid
State Relay in one small industry standard package. The MCPC
uses microprocessor control relay logic, accepts a wide range
input logic power supply, provides an output load status
indicator, and five modes of analog control input along with an
Enable/Disable control.
The Crydom MCTC is a unique self-contained state of the art basic
Temperature Control Relay that combines all the necessary functions
into one easy to set up and use standard size package. The MCTC
is ideal for temperature control users that do not need multiple
built-in options, displays, and functions that they will never use.
The MCTC requires only a single, non-regulated low current DC
source, (10-32Vdc at 32mA max.), and a type J or K thermocouple,
to be able to accurately control heater and cooling compressor
loads up to 530Vac at 90A. The unit incorporates an internally
compensated thermocouple input, 5 available temperature ranges
including an inverse function refrigeration version, with adjustable
setpoint using analog low voltage or 4-20mA inputs, separate
output enable/disable control, and built in Crydom Solid State Relay
technology for load control. With integrated zerocross burst firing,
and proportional derivative control to avoid set-point overshoot†,
the unit also includes 2 LED status indicators for visual reference of
operation and setpoint conditions.
The MCPC does not require any calibration adjustment, is
optically isolated to 4000Vrms, includes an internal snubber
network, and is available in load ratings up to 90A and 530Vac.
The Crydom MCPC series is particularly suited to applications
such as tungsten lamp dimming, vibratory feeders, universal
motor control, and resistive heating element control.
