SAFETY

Field wiring protection

• [EEx ia] IIC

Safety Description (each channel)

• Channels 1. 2. 3. 4. 7 and 8. wired as separate

IS circuits – Uo = 16.4 V, Io = 79 mA, Po = 0.33 W

Channels 5 and 6. wired as separate IS circuits –

Uo = 1 V, Io = 1.1 mA, Po = 0.3 mW

(Input terminals are equivalent to non-energy storing apparatus)

FM entity parameters

• Channels 1. 2. 3. 4. 7 and 8. wired as separate IS

circuits – Voc = 16.4 V, Isc = 63.7 mA, Po = 131mW

• Channels 5 and 6. wired as separate IS circuits –

Uo = 1 V, Io = 1 mA, Po = 0.25 mW
