RS232 Port DB9 female DCE 9600 baud, no parity, 8 data bits,
1 stop bit
Inputs
Digital/Pulse Inputs 2 inputs Suitable for voltage free contacts,
NPN transistor or TTL signal
Pulse Inputs Transmitted as 2 x 16 bit
counters, plus pulse rate
value Share digital inputs. Max rate
300Hz for contact or transisitor
inputs, 10KHz for TTL inputs
(50KHz on PI2 using divider)
PI2 has a configurable 1-255
integer divider
Max value for pulse rate is
1KHz.
Analogue Input One 0 - 24 mA, 0 - 10 V
Range user-configurable
“floating” differential input,
common mode voltage 24V.
24V DC for powering external
loops provided, 50 mA max.
Resolution 12 bit, Accuracy <
0.1%. Transducer warm-up time
configurable 1 - 100 seconds.
Analogue Input Setpoint Configurable high & low setpoint
may be transmitted to remote
units,
allowing set/reset of
remote digital outputs
System Parameters
Network Configurations Max. number of 505K
inputs is >20 000 if
105U-C
modules are
used as receivers.
505K is compatible with 105U
radio telemetry units which may
be used as repeaters, provision of
outputs, or as network master
unit to connect to PLC or PC
