Product Highlights
Each input channel of the SPR-24 is independently configurable for either Long or Short output pulse mode. In Long mode, the output pulse width mirrors the input pulse duration exactly, making it ideal for standard energy pulse applications. In Short mode, the output is fixed at 100 milliseconds regardless of input duration — well suited for end-of-interval pulses or applications where a consistent, fixed-width output is required by the downstream device.
Built-in MOV transient protection on all solid-state relay contacts eliminates the need for external suppressors, and the polycarbonate enclosure and base plate provide maximum user protection and excellent electrical insulation from the mounting surface. The SPR-24 is intended for installation inside a user-supplied enclosure appropriate for the operating environment.
Features
- Two independent input channels — accepts two Form A (2-wire) or Form C (3-wire) inputs, each with +13VDC sense voltage supplied to the meter's Y and Z terminals.
- Four isolated Form C outputs — four solid-state dry-contact KYZ outputs; each switch-selectable to follow either input channel independently.
- Flexible output assignment — any combination of outputs can follow either input; one input can control one, two, three, or all four outputs.
- Long and Short pulse output modes — Long mode mirrors input pulse width; Short mode produces a fixed 100mS output closure per input transition.
- High-speed pulse rated — handles up to 72,000 pulses/hour in 3-wire mode and 36,000 pulses/hour in 2-wire mode.
- Wide voltage range power supply — built-in low-voltage transformer-isolated supply; compatible with high and low voltage semiconductor and mechanical meter outputs.
- Built-in MOV transient protection — eliminates the need for external or off-board transient suppressors on all four output contacts.
