Intrinsically Safe Modules The following is a CSA certified wiring diagram for this module. Notes related to CSA certification for this module. Note 1. Entity parameters per channel: Voc = 23.8 V Isc = 112 mA Ca = 127nf NON-HAZARDOUS LOCATION (SEE NOTE 1) V1 (-) (See Note 2) N/C Note 2. Maximum nonhazardous area voltage must not exceed 250 V. Note 3. Install in accordance with Canadian Electrical Code, Part I for installation in Canada. Note 4. Install in accordance with the NEC (ANSI/NFPA 70) and ANSI/ISA RP 12.6 for installation in the United States. Note 5. To maintain intrinsic safety, shield for each cable must be grounded and must extend as close to the terminals as possible. V2 (-) Note 7. I.S. devices when connected to I.S. terminals must satisfy the following conditions: Voc < Vmax Isc < Imax Ca > Ci + Ccable La > Li + Lcable Note 8. This module is certified as a component for mounting in a suitable enclosure where the suitability of the final combination is subject to acceptance by CSA or an inspection authority having the jurisdiction. V1 (+) V2 (+) Signal 2 N/C N/C V3 (-) N/C I.S. 3 wire transmitter I.S. + 14.5 Vdc Signal 1 N/C Chassis Ground (See Note 1) V3 (+) Signal 3 (SEE NOTE 1) V4 (-) N/C N/C V5 (-) N/C V6 (-) N/C Note 6. intrinsically Safe (I.S.) cables of one module must be routed separately from I.S. cables of another module. HAZARDOUS LOCATION ZONE 1 GROUP IIA, IIB, IIC N/C V7 (-) N/C V8 (-) V4 (+) I.S. 2 wire transmitter Signal 4 N/C V5 (+) Signal 5 Chassis Ground (See Note 1) V6 (+) Signal 6 Note 1. Only shielded twisted pair cables should be used for connections. Shields should be left open at the field end and connected to chassis ground at the ground screws on the backplane. Note 2. A dropping resistor 100 Ohms is across the signal and V(-) pins of each channel. V(-) is internally connected to I.S. ground. N/C V7 (+) Note 3. Three wire transmitters should be provided power only from the module. An external power supply should not be used. Signal 7 V8 (+) N/C Signal 8 N/C N/C Note 4. Pins marked “N/C” (Not Connected) are not electronically connected to the module. I.S. Module AII 330 10 Blue Terminal Strip 31001363 Rev 00 Note 5. Only Quantum 140 XBP 0X 00 backplanes should be used for mounting this module. 140 AII 330 10 Wiring Diagram 449 35013379 02 October 2007 This document provided by Barr-Thorp Electric Co., Inc. 800-473-9123 www.barr-thorp.com
