The Type 9470 Digital Input Module is designed to receive up to 16
discrete input signals from dry contacts and NAMUR proximity sensors
etc. and transfer them to the IS1 CPU & Power Module. The module is
intrinsically safe for installation in a Class I, II, III, Division 1, Group A-
G or Class I, Zone 1, Group IIC/IIB hazardous location according to
NEC Article 504/505 and provides intrinsically safe connections for
Class I, Division 1, Groups A-G or Class I, Zone 0, Group IIC/IIB
hazardous locations listed below.

Notes:
1. Intrinsically safe apparatus shall be switches or an FM approved
System or Entity device connected in accordance with the
manufacturer´s installation instructions.
2. For Entity concept use the appropriate parameters from above to
ensure the following:
