Time Delay Relays Dedicated - Dual Function KRPD SERIES Relay Output Timer Description The KRPD Series is a factory programmed time delay relay available with 1 of 12 standard dual functions. The time delays can be factory fixed, onboard or externally adjustable or a combination of fixed and adjustable. The SPDT output relay contacts offer a full 10A rating with complete isolation. Its microcontroller timing circuit provides excellent repeat accuracy and stability. Encapsulation protects against shock, vibration, and humidity. The KRPD Series is a cost effective approach for OEM applications that require small size, isolation, accuracy and long life. Features & Benefits FEATURES BENEFITS Microcontroller based Repeat Accuracy + / - 0.5% Compact design Allows flexiblility for OEM applications Isolated, 10A, SPDT Allows control of loads for AC or DC voltages output contacts Encapsulated to protect against shock, vibration, Encapsulated and humidity Accessories Wiring Diagram P1004-95, P1004-95-X Versa-Pot Panel mountable, industrial potentiometer L1 N/L2 V = Voltage recommended for remote time delay adjustment.
