DH48S-1Z Digital Time Delay Relay (On-Delay, 8-Pin)

The DH48S-1Z is the standard digital time delay relay found in control panels and machine builds across Pakistan, timing from a hundredth of a second up to 99 hours off a set of five thumbwheel dials rather than a fiddly analogue knob, so the delay can be dialled in precisely and read back at a glance on its 4-digit LED display. Once power is applied it counts down and then switches its single SPDT contact, giving either a delayed-start or delayed-cutoff function depending on how it's wired; dedicated gate and reset terminals let an external signal pause the countdown or force it back to zero without cycling power to the whole relay. Its 5A 250V AC contact and 8-pin octal base drop straight into the same sockets used across the DH48 family, so it's a common upgrade or replacement part. It's built for motor start sequencing, conveyor and pump delay control, and any automation or electrical panel job needing an accurate, easily field-adjustable time delay.
