I/O OPTIONS

■ Event Trigger Input: Dry contact or NPN open collector

Input current: ≤ 3 mA

Sensing: 6 V

Contact detecting: ≤ 1.5 V at ON; ≥ 3 V at OFF

Signal ID and Details

S-TMR: Startup Timer

Measuring starts in the predetermined time after detecting

the signal turning on.

TIMING: Timing

Used for various timing hold functions

ZERO: Forced Zero

Forced Zero and tare adjustment are externally controlled

when ZERO signal is turned on/off.

HOLD: Hold data

Reading measured signal stops and the last

value is held when HOLD signal is turned on.

RESET: Reset data

The device is reset when RESET signal is turned on.

■ Alarm Output: Relay contact

Rated load: 250 V AC @ 3 A (cos ø = 1)

30 V DC @ 3 A (resistive load)

Maximum switching voltage: 250 V AC, 30 V DC

Maximum switching power: 750 VA, 90 W (resistive load)

Minimum load: 5 V DC @ 10 mA

Transmission: Half-duplex, asynchronous, no procedure

Interface: Conforms to TIA/EIA-485-A

Max. transmission distance: 500 meters

Baud rate: 1.2 – 38.4 kbps

Max. number of nodes: 31 (except the master)

Protocol: Modbus RTU

Parity: None, odd or even

Stop bit: 1 bit, 2 bits
