Environment and installation

Ambient temperature

Operation and storage:

• variant 12…36 V DC: 0…+ 60 °C (+ 32…+ 140 °F)

• variant 115/230 V AC: 0…+ 50 °C (+ 32…+ 122 °F)

1.4. Batch controller

Note:

If the device is mounted in a humid environment or outside, then the maximum voltage allowed is 35 V DC instead of 36 V DC.

Electrical data

Operating voltage (V+)

• 12…36 V DC, max tolerance: - 5 % or + 10 % at 12 V DC, ± 10 % at 36 V DC, filtered and regulated

Connection to main supply: permanent, through external SELV (Safety Extra Low Voltage) and LPS

(Limited Power Source) power supply

• 115/230 V AC, 50/60 Hz

Voltage supply available inside the device:

– supplied voltage: 27 V DC regulated

– maximum current: 125 mA

– integrated protection: 125 mA time delay fuse

Current consumption

With sensor, without consumption of digital input and pulse output

• With relays:

– ≤ 100 mA (at 12 V DC)

– ≤ 50 mA (at 36 V DC)

– ≤ 55 mA (115/230 V AC)

• Without relay:

– ≤ 70 mA (at 12 V DC)

– ≤ 35 mA (at 36 V DC)

– ≤ 40 mA (115/230 V AC)

Power consumption

115/230 V AC powered measuring device: 3 VA

Input

• DI (1 to 4)

• Switching threshold V

on: 5…36 V DC

• Switching threshold V

off max.: 2 V DC

• Min. pulse duration: 100 ms

• Galvanic insulation, protected against polarity reversals and voltage spike

Output

• Transistors (digital outputs DO1 and DO4):

– potential-free
