When the TIO device is set as the last device on the RS-485 bus segment and

220 Ohm bus termination is required, set the jumper J2G to position 19-20. This

will result in connection 220 Ohm resistor between RS-485 (+) and (-) terminals.

4.5 Digital and Pulse Optically-Isolated Outputs

Connections

TIO is equipped with two programmable digital optically-isolated outputs. Each

output can be assigned to any one of many different system events or config-

ured as a pulse output (see Paragraph 5.3.9).

Digital optically-isolated outputs use dedicated 4 position 3.5mm male terminal

block header J1 located on the top side of the TIO enclosure (see Figure 6.1).

(Mated interface connector: Tyco Electronics P/N: 284510-4).

Optocoupler #1 - Terminal J1 (pins 1 and 2):

Plus (+) (passive) --------------- Terminal J1 pin 1

Minus (-) (passive) --------------- Terminal J1 pin 2

Optocoupler #2 - Terminal J1 (pins 3 and 4):

Plus (+) (passive) --------------- Terminal J1 pin 3

Minus (-) (passive) --------------- Terminal J1 pin 4

WARNING: Optically-isolated outputs require application of external

DC voltage across terminals. Do not exceed maximum allowed

limits for voltage and current provided below:

2 V < UCE < 40 V

0.2 mA < ICE < 150 mA
