Detailed data
GE IC200ALG320 Analog Input Module
The Current Source Analog Input Module (IC670ALG230) accommodates eight inputs on a common supply.
Power Sources:
In most cases, the same 24 volt supply used by the bus interface unit can provide loop power. If isolation between circuits is required, a separate supply must be used. The most common application is to drive multiple isolated sensors, isolated analog inputs, or differential analog inputs using loop power local to the module.
LED:
An LED, visible through the transparent portion of the module top, is on when both backplane and field power are present, and the fuse is not blown.
Field Wiring:
The input signals share a single signal common return. For good noise immunity, establish a system signal common, power reference point, and ground close to such single-point terminals. The signal common of the input module (defined by most standards) is the negative terminal of the 24-volt power supply. The chassis ground of the module is connected to the I/O terminal block ground terminal. For improved noise immunity, connect it to the chassis of the housing with a short wire.
Two-wire loop-powered transmitters (Type 2) should have isolated or ungrounded sensor inputs. The loop-powered device should use the same power supply as the input module. If a different power supply must be used, connect the signal common to the module common. In addition, ground only one point on the signal common, preferably at the input module. If the power supply is not grounded, the entire analog network is at floating potential (except for the cable shield). Therefore, if this circuit has a separate isolated power supply, it can be isolated.
If shielded wire is used to reduce noise pickup, the shield drain wire should have a different ground path from any loop power ground to avoid noise caused by leakage current.
Three-wire transmitters require a third wire for power. The shield can be used as a power return. If the system is isolated, a third wire (three-wire cable) should be used instead of the power shield, and the shield should be grounded.
A separate remote power supply can also be used. A floating power supply should be used for best results. Grounding both supplies creates a ground loop. Despite this, the circuit may work, but good results require very good voltage compliance on the transmitter.
