Sylvania PMT 7313 Timing Relay 120V Coil 60 Hz

The Sylvania PMT 7313 timing relay (713UP variant) is a pneumatic time-delay relay in the Joslyn Clark PMT Bulletin 7313 family, designed for 120 V AC operation at 60 Hz. This open-type relay includes a timing head and an operating coil, enabling precise delays in control circuits without requiring mechanical relays. The PMT 7313 family provides a wide timing window, typically from 0.2 seconds up to 3 minutes, allowing users to configure short on-delays, off-delays, or signaling intervals to suit sequencing tasks. In common 713UP offerings, the contact arrangement is Form C (one normally open and one normally closed), making it suitable for interlocks, sequencing, alarms, and load control where a timed output is needed after energization or de-energization. The unit is intended for industrial environments and is compatible with standard control panels and relay bases used in machine automation, process lines, and safety circuits. With its 120 V AC coil and 60 Hz operating specification, it integrates with typical North American power systems and industrial control architectures, delivering reliable timing performance in a compact package that can be mounted in standard enclosures or relay racks.
