Imax=125 mA

Pmax = 900 mW

Ci = 4 nF

Li = 10 uH

7.5 SVi1000 (+) and (-) Position Retransmit (4-20mA Output) Terminals

These terminal provide the 4-20mA position retransmit output and are equipped only on the

Position Retransmit Terminal board. A transmitter type barrier with 250 Ohm series resistance

(internal or external) could be used for this connection.

Entity Parameters:

Vmax= 30 Vdc

Imax=125 mA

Pmax = 900 mW

Ci = 8 nF

Li = 1 uH

7.6 Entity Requirement

Cable capacitance and inductance plus the I.S. apparatus unprotected capacitance (Ci) and

inductance (Li) must not exceed the allowed capacitance (Ca) and inductance (La) indicated

on the associated apparatus. If the optional Hand Held Communicator is used on the

Hazardous Area side of the barrier, then the capacity and inductance of the communicator

must be added and the communicator must be agency approved for use in the hazardous

area. Also, the current output of the Hand Held Communicator must be included in the current

output of the associated equipment.

The barriers may be active or passive and from any certified manufacturer as long as the

barriers comply with the listed entity parameters.

7.7 Installation Restriction

A device which has previously been installed without an approved IS barrier must NEVER be

used subsequently in an intrinsically safe system. Installing the device without a barrier can

permanently damage the safety related components in the device making the device

unsuitable for use in an intrinsically system.

Repair

WARNING: EXPLOSION HAZARD – SUBSTITUTION OF COMPONENTS MAY IMPAIR SUITABILITY

FOR USE IN A HAZARDOUS LOCATION.

Only qualified service personnel are permitted to make repairs on the SVi1000 positioner.

Replace ONLY with genuine GE parts.
