Section 5. Measurement and Control Peripherals
51
In other applications it may be desirable to simply switch power to a device
without going through a relay.
FIGURE. Power Switching without Relay
(p. 51)
illustrates a circuit for switching external power to a device without using a
relay. If the peripheral to be powered draws in excess of 75 mA at room
temperature (limit of the 2N2907A medium power transistor), the use of a relay
is required.

TIMs
Terminal Input Modules (TIMs) are devices that provide simple measurement
support circuits in a convenient package. TIMs include voltage dividers for
cutting the output voltage of sensors to voltage levels compatible with the
CR200(X), modules for completion of resistive bridges, and shunt modules for
measurement of analog current sensors. Refer to
APPENDIX. Signal
Conditioners
(Appendix p. 32) for information concerning available TIM
modules.
