Terminal/Pin Configuration
Outputs: Pins 1,3,4,5,6, and 8 are the terminals for
the H3CA-8H internal output relays.
Relay #1: Is an instantaneous contact. Which means
this relay will immediately switch when power is apply
to timer.
Pin 1 is the COM for relay #1.
Pin 3 is the NO contact for relay #1.
Pin 4 is the NC contact for relay #2.
Relay #2: Is a timed contact. Which means this
relay will only switch at the end of the time delay
period.
Pin 8 is the COM for relay #2.
Pin 6 is the NO contact for relay #2.
Pin 5 is the NC contact for relay #2.
Because both internal relay outputs are totally
different in function. Please make sure not to wire
these relays together in an application.
Outputs: Pins 1,3,4,5,6, and 8 are the terminals for

Pin 1 is the COM for relay #1.
Pin 3 is the NO contact for relay #1.
Pin 4 is the NC contact for relay #2.
Pin 8 is the COM for relay #2.
Pin 6 is the NO contact for relay #2.
Pin 5 is the NC contact for relay #2.
