*Analog inputs may be jumpered internally (249 1 resistor) for two-wire or three-wire
0 to 20 mA range input.
**Discreet inputs are pulled up internally to logic high of 5 V dc. These inputs may be
activated, pulled low, with relay contact, open collector BJT, or open drain FET.
***Discreet outputs can handle up to +50 V dc and 115 mA dc (open
drain MOSFET).
*Note: Because of protection op-amps, which are rail-to-rail input and output
devices, the voltage to the
Y P internal 10 bit A/D converters is limited to 4.950 V.
