Crydom PMP Series solid state relays control load power in proportion to an analog control input, including a 0 to 5VDC or 0 to 10VDC voltage or a 4-20mA DC current. Fully configurable, they have a selectable operation mode that allows using phase angle or burst fire control. The relays are C-UL-US recognized and CE compliant to the Low Voltage and RoHS Directives.
