Sample Sequencer

Appendix H

Notes:
mA Configuration (Default Assembly)
R44=Zero ohm jumper installed.
J1=No component installed.

0-1 VDC Configuration
1. Remove Zero ohm jumper R44.
2. Install a 37 ohm resistor

1

at J1.


0-5 VDC Configuration
1. Remove Zero ohm jumper R44.
2. Install a 237 ohm resistor

1

at J1.


0-10 VDC Configuration (Use this config. with a Floating (isolated) or -10VDC Power Supply

2

)

1. Remove Zero ohm jumper R44.
2. Install a 487 ohm resistor

1

at J1.

3. Tie the "+" to "AGND" on TB2 with a jumper wire.

0-10 VDC Configuration (Use this configuration with a +10VDC Power Supply.

2

1. Install a 487 ohm resistor

1

to "+" on TB2. Connect the Vin positive wire to the resistor.

Sentry Equipment recommends soldering the positive wire to the resistor, and covering the

solder connection with heat shrink tubing.

To determine the power supply type, use an Ohm Meter and measure the resistance

from the positive terminal to ground or negative terminal to ground. If the resistance is
<100 ohms between the positive terminal and ground, it's a - 10 vdc power supply. If the
resistance is <100 ohms between the negative terminal and ground, it's a +10 vdc
power supply. If the resistance is >100 ohms in either case, it's a floating 10 vdc input.
