  • This unit can control a compressor, motor, pressure, valve, humidity, as well as thermal processes.
  • The serial communications when used with the free WATLOW software, saves time of controller setup.
  • P3T armor sealing system Complies to NEMA 4X, IP66

Updated EZ-ZONE® Features

  • Also available for line voltage from 100Vac up to 240Vac Model PM4C1CA-AAAABA

Universal Input

  • This can be a thermocouple grounded or ungrounded
  • It can be an RTD 2-wire or 3-wire
  • It can be 0-20mA or 0-50mV

Switched DC Specifications:

  • 30mA DC Maximum Supply Current
  • Short Circuit Limited to < 50mA
  • 22 ~ 32V -DC Open Circuit Voltage
  • Drives External Relay Using dc- and dc+

Open Collector Specifications:

  • Current Sinking Output @ 100mA Maximum
  • Maximum Supply Voltage -30VDC
  • For DC Loads An External Power Supply Is Required
  • Connect Load Negative To Open Collector

NOTE: Switching Pilot Duty Devices Such As Control Coils For Relays Or Contactors Produces An Electro-Magnetic Force When De-Energizing Those Type Of Loads. To Protect The Controller's Electronic Circuitry From The Inductive User Load, The Use Of An RC Suppressor Also Known As A Snubber Device Should Be Wired Between The Load And The Load Output Terminal Of The Controller. An Exception Is The Use Of Watlow Solid State Relays Having Internal RC Suppression.

Two Wire Bus Communication Interface Type EIA-485 Also Known As RS-485 Comes Standard With All PM Series Controllers Which Can Provide An Easy Alternative to Setting Up Program Menu Options. Various Profiles Can Be Configured And Saved As Files And Can Be Up Loaded To Other PM Controllers. USB To Serial Converter Is Required To Connect The PM Controller To Any Computer With A USB Port.
