RMC150 Quadrature Wiring

This topic covers the wiring of the quadrature inputs on the RMC150 Quadrature (Q) module. For the Control Output (Drive) wiring, see the RMC150 Control Output (Drive) Wiring topic. For wiring quadrature inputs on the Universal I/O Module, see the RMC150 UI/O Wiring.

Use shielded twisted pairs for all connections to inputs and outputs. Route the transducer wiring separate from other wiring. You must provide the power supplies needed by your transducers. See Wiring Guidelines for general wiring information.

Note:
The example schematics do not include transducer pin numbers, color codes, or power supply requirements, since these vary between different transducers. To determine your power supply needs and connector pin-outs or cable color codes, consult your transducer manufacturer's documentation.

Note:
The Quadrature input Cmn pin must be connected! A disconnected Cmn pin can cause noise and inaccurate readings.

Fault Input Wiring

The Fault input is compatible with signal levels ranging from 12V to 24V. The Fault Input draws 2.7mA maximum and turns on at 6V. The Fault input turns on when a current flows. The polarity of the voltage is unimportant. See the Fault Input topic for more details.

Enable Output Wiring

The Enable output is a solid state relay (SSR). When it is off, it has high impedance, and when on it has low impedance (10 Ω maximum). Because the Enable output is isolated, the user must power it externally. The maximum current and voltage for the Enable output is 100 mA and 30 V.

The Enable output has a + and - connection. Both lines must be connected for the output to function. Because both sides of the output are provided, the switches may be independently connected in a high side or low side configuration (that is, with the load (input) on the source or sinking side of the output). See the wiring diagrams below.

See the Enable Output topic for more details on the Enable Output.

To active low Enable input:

Using Outputs with Inductive Loads

External fuses should be used to protect the SSRs if there is a possibility of over-current. When switching inductive loads, it is important to place a diode or tranzorb across the load to protect the switch when transitioning from an “ON” to an “OFF” state. Otherwise, the collapsing magnetic field can cause a reverse voltage spike in excess of the 30 V rating of the SSR.

Control Output Wiring

The valve or motor drive connects to the following MAx pins:

Pin	Function
Control Output	Control Output
Cmn	Control Output Common. Each axis has two Cmn pins. Either of the 2 pins may be used.

See the Control Output topic for more details on the Control Output.

Note:
The Control Output polarity can be set with the Invert Output Polarity parameter.
