Product Highlights
The RTR-2C operates in two output modes: Normal mode, where the output mirrors the input pulse duration, and Fixed mode, where a selectable output closure time (5, 10, 20, 50, 100, 200, 500, or 1000mS) is generated regardless of input pulse width — enabling both pulse stretching for slower downstream equipment and pulse shortening for high-rate applications.
If input pulses arrive faster than the output can deliver them, the RTR-2C’s microcontroller stores up to 65,535 pulses in a buffer and delivers them in a 50/50 duty cycle, ensuring no pulses are ever lost.
A yellow LED displays input pulse status and a green LED confirms output status at all times, with a red overflow LED lighting if the 65,535-pulse buffer is exceeded.
Features
The SSI RTR-2C is a DSP-based high-speed water and gas meter relay handling up to 200 pulses per second with two isolated outputs, 65,535-pulse buffer, and 8 selectable filter times.
- Up to 200 pulses per second — DSP-based design handles high-speed water and gas meter pulse rates with reliable accuracy.
- 8 selectable input filter times — 25µs to 20mS in eight steps; rejects noise while accepting valid high-speed pulses.
- Two isolated Form A outputs — dual independent KY solid-state dry-contact outputs for two downstream devices from one meter.
- Normal and Fixed output modes — Normal mirrors input timing; Fixed generates 5–1000mS output closures for pulse stretching or shortening.
- 65,535-pulse output buffer — stores excess pulses during high-rate bursts; delivers in 50/50 duty cycle to prevent pulse loss.
- Onboard 12V/20mA meter power output — directly powers water or gas meters that require an external supply voltage.
- Yellow, green, and red LED indicators — display input status, output status, and overflow condition independently.
