The Macromatic TR-6816U is a multi-function Time Delay Relay. This programmable multi-range plug-in relay has a universal input voltage of 24-240V AC & 12-125V DC at 50/60Hz, with 10A SPDT output contacts. It has 16 built in time ranges, from 0.05 sec to 100 hours, selected using a rotary switch. A potentiometer makes precise adjustments within the time range. Time delay function is also selected using a rotary switch. The TR-6816U uses an 8 pin 70169-D octal socket. Note: Image is an approximation. Actual part may differ.
