Multifunction Time Delay Relay

The Macromatic TD-88161 is a plug-in industrial relay designed for automation and control panels. It suits engineers and maintenance technicians who need programmable timing logic in a standard octal socket. The enclosed, transparent housing allows visual inspection while meeting IP20 protection requirements. This new unit provides 16 selectable delay functions for diverse sequencing tasks.

16 Selectable Delay Functions

A single DIP-switch adjustment selects one of 16 timing modes, covering on-delay, off-delay, interval and repeat-cycle operations. The timing range spans from 0.05 sec up to 10, 230 hr, eliminating the need for multiple dedicated relays. SPDT contacts rated at 10 A handle 240V AC or 30V DC loads directly. The 240V AC coil voltage matches common industrial control circuits.

Octal Socket Integration

The 8-pin octal base plugs into standard DIN-rail or panel-mount sockets, simplifying installation and replacement without rewiring. Flat-pin compatibility ensures a secure connection in existing enclosures. The relay frees up panel space by consolidating multiple timing functions into one module. It requires a suitable 240V AC supply and a standard octal socket to operate.

Questions about this item

What does the 16 delay functions mean when the relay is installed in a control panel?

The relay offers 16 selectable timing modes such as on-delay, off-delay, interval and repeat-cycle, all set by the on-board dip switches so one device covers many timing tasks.

How does the octal plug-in base limit the relay in a real installation?

The eight-pin octal socket carries power, coil and SPDT contacts in a standard industrial footprint, so the relay plugs into any matching octal base but cannot be hard-wired directly.

What mounting space and wiring does the IP20 enclosed relay need?

It mounts by plugging into an octal socket on a DIN rail or panel, requires no tools beyond the socket wiring, and the IP20 enclosure means it must sit inside a protected cabinet.
