Honeywell Analog Outputs 0 to 20mA (16 channel, 2 modules per rack)900B16-0101
4 Channel Pulse/Frequency/Quadrature Module - DC Voltage type (900K01-xxxx) (cont’d)Pulse Output Specifications
Channels Used Any one of the channels can be used for Pulse Output.
However, the use of a particular channel for outputting pulses
will render the particular input channel unusable for either of
pulse, frequency or quadrature input.
Digital Output Type Open Collector, 5 to 24V, 30 mA max
Frequency Range 25 Hz – 10 KHz
Duty cycle Always 50%
Pulse Output Duration Selectable CONTINUOUS or NUMBERED PULSES.

Safety Universal Input /Output Module (900U02-xxx)
Safety Universal Input/ Output (UIO) provides 16
universal channels. Each channel of the module can be
soft configured as AI, AO, DI or DO. Features
supported by UIO are :
Channels soft configurable as AI, AO, DI or DO (All
channel are sourcing type)
SOE (Sequence of Events) with resolution of 1 mS
Simplified wiring for SIL-2 applications due to
single module solution.
Line Monitoring for all configurations.
Short circuit protection for DO
Per channel Safety Shutdown eliminates need for
external master relay.
A green blinking status LED on the module indicates
when the module is being scanned. A red status LED
when module or channel diagnostics exist.
For channels configured as Digital input a closed
external circuit causes current flow from UIO to
establish an ON state. Logic in the controller allows this
state to be inverted when necessary.
Analog outputs can only be configured on channels 9 to
16. The Analog Output provides 4 to 20 mA outputs that
may be scaled by the user to any span within this range
on a per output basis.
Digital Outputs provide over current protection .. In case
of short circuit for any output channel, that channel is
switched off. Power cycling is not required to reset the
module.
For channels which are configured as output (AO/DO) a
user specified failsafe value is supported to allow
predictable operation in the event of a communication
loss between controller and IO module.
Requires 20 pin-terminal terminal block.
