GENERAL SPECIFICATIONS |
Power supply | | 12 Vdc to 30 Vdc (4-20 mA model) or 18 to 30 Vdc (0-10 V
model) |
Outputs | : | 4-20 mA or 20-4 mA current, 2-wire loop power supply, 0-10
Vdc voltage (optional) |
OUT1 output resolution | : | 0.006 mA (4-20 mA) or 0.003 V (0-10 V); |
OUT2 output resolution | : | 0.022 mA (4-20 mA) or 0.015 V (0-10 V); |
Channel isolation | : | The 4-20 mA outputs are isolated from each other. The 0-10 V
outputs share a common ground; |
Output Load (RL) | | 4-20 mA output: RL (Ohms max) = (Vdc – 12) / 0.02
Let Vdc = Loop power supply (12 to 30 Vdc)
0-10 Vdc output: RL (min) = 10 kilo ohms |
