Description
- Auxiliary switching device
- ExH-A
- For galvanic isolation between the
- ball immersion switches used in the Ex area
- and a control system.
- The auxiliary switching device is used to place the
- immersion switches or other control devices
- in "intrinsically safe circuits" of the
- protection type EEx ib IIC.
- Since only the control circuits are intrinsically safe
- , the device must be installed outside the potentially explosive
- area
- . Control for 1N/PE x 230 V,
- 50 Hz operating voltage. Equipment:
- 1 ISO enclosure with transparent cover, IP 54
- (HxWxD) 180 x 130 x 100 mm, with
- PG cable glands H = 220 mm
- 1 auxiliary switching module Ex II (with 2 intrinsically
- safe circuits)
- 1 sticker for labeling the
- intrinsically safe lines
- The auxiliary switching device requires
- its own power supply.
- If the mains power fails, the transmission of a switching command is therefore only possible via the battery, which is available as an accessory.
- Connection options and an integrated charging circuit are already available as standard.
- A battery must also be used for the mains-independent supply of the alarm system in the downstream control.
