Type 9170/11-1*-21 (1 channel)
Hazardous area:
Class I, II, III; DIV 1; Group A-G or Class I; Zone 0; Group IIC/IIB Hazardous Locations
Safe area:
Non-hazardous
The Switching Repeater Type 9170 is an associated apparatus for installation in non-hazardous locations and provides intrinsically safe
connections for one (or two) field devices located in Class I, II, III, Division 1, Group A-G or Class I, Zone 0 [AEx/Ex ia] Group IIC,
hazardous locations according to NEC and CEC as listed below. The I.S. inputs are limited with linear characteristic.
Type 9170/a1-1d-21
a = numeral 1 or 2 for number of channels
d = numeral 0, 1, 2 or 3 for characterising the output
Entity parameters for wiring configurations are as follows:
Type 9170/*1-1*-21
Two input circuits in parallel
Maximum supply current (at 96 V AC, terminals L and N):
9170/11-1*-21
11.3 mA
9170/21-1*-21
19.5 mA
Notes:
1.
For Connections refer to chapter Commissioning of the provided Operating Instructions.
2.
Intrinsically safe apparatus may be switches, thermocouples, LEDs, RTDs or a third party certified system or
Entity device connected in accordance with the manufacturer´s installation instructions.
For Entity concept use the appropriate parameters to ensure the following:

For installations in which both the Ci and Li of the intrinsically safe apparatus exceeds 1% of the Ca (or Co) and La (or Lo)
parameters of the associated apparatus (excluding the cable), then 50% of Ca (or Co) and La (or Lo) parameters are
applicable and shall not be exceeded. The reduced capacitance shall not be greater than 1 μF for Groups C and/or D, and
600 nF for Groups A and B.
3.
This associated apparatus has not been evaluated for use in combination with another associated apparatus.
4.
Electrical apparatus connected to an intrinsically safe system should not use or generate voltages > 250 V (U
5.
Installation should be in accordance with Article 504/505 of the National Electrical Code, ANSI/NFPA 70 and
ANSI/ISA RP 12.06.01.
6.
Installation in Canada should be in accordance with the Canadian Electrical Code,
7.
Use a general purpose enclosure meeting the requirements of IEC 61010-1 for use in non-hazardous.
8.
These modules are to be mounted on DIN rail. The I.S. field wiring in any case is connected to the ISpac device terminals.
