OUTPUT
DIGITAL OUTPUT
Function
Transmitting compensated accumulated total (scaled pulse) or input pulse retransmission
Scaled output
Output D1: max. frequency 500 Hz.
Output D5: max. frequency 4 Hz, recommended use below 0.5 Hz
Pulse length user definable between 1msec up to 10 seconds
Retransmission output Square wave output based on frequency of (sine wave or coil) input signal. Maximum frequency
10kHz with a 50% duty cycle, minimum on and off-time 50µs
Type OT
One passive transistor output (NPN) - not isolated. 300 mA – 50 V @ 25°C
Type OR
One isolated electro-mechanical relay output (NO).
Maximum resistive load: 2A @ 250 VAC / 30 VDC.
Maximum inductive load: 0.5 A (pilot duty applications).
Note 1: Requires 24 – 27 VDC and supplied via P5 - P6.
Note 2: Type OT remains available.
Note 3: Not used in pulse retransmission mode
