Sensor inputs
Thermocouple (TC) processing : Accepted TC types and temperature ranges:
• Type E (NiCr-CuNi): −270 to +1000°C (−454 to +1832°F).
• Type J (Fe-CuNi): −210 to +760°C (−346 to +1400°F), API 670 standard.
• Type K (NiCr-NiAl): −270 to +1372°C (−454 to +2501°F).
• Type T (Cu-CuNi): −270 to +400°C (−454 to +752°F).
• User-defined (user entry of linearising polynomial functions). Accuracy: 0.3°C (0.54°F) or 0.3% of measuring range. Resolution: 0.1°C (0.18°F).
Resistance temperature detector (RTD) processing
: Accepted RTD types and temperature ranges:
• Pt100, 100 Ω at 0°C, 3-wire and 4-wire platinum RTD (alpha = 0.00385): −200 to +850°C (−328 to +1562°F), API 670 standard.
• Pt100, 100 Ω at 0°C, 3-wire and 4-wire platinum RTD
(alpha = 0.00392): −200 to +700°C (−392 to +1292°F).
• Ni, 120 Ω, 3-wire and 4-wire nickel RTD: −80 to +260°C
(−112 to +500°F).
• Cu10, 10 Ω at 25°C, 3-wire and 4-wire copper RTD: −100 to +260°C
(−148 to +500°F).
• User-defined (user entry of linearising polynomial functions).
Accuracy: 0.3°C (0.54°F) or 0.3% of measuring range, except for Cu10
(1°C (1.8°F) or 1% of measuring range).
Resolution: 0.1°C (0.18°F).
Accepted RTD wiring schemes: 2-, 3-, and 4-wire for any RTD type. DC current (process input) processing • Total range 0 to 25 mA.
• Measuring resistor 50 Ω.
• Fuse-protected with 50 mA self-resetting fuse. Resistance seen from
input: the sum of fuse and measuring resistor resistance is maximum
100 Ω, typically 55 Ω.
• Positive polarity input only.
• Accuracy: 0.5% of total range, that is, 125 µA. DC voltage (process input) processing • Total range 0 to 10 V.
• Input resistance 100 kΩ.
• Positive polarity input only.
• Accuracy: 0.5% of total range, that is, 50 mV. Cold-junction compensation (CJC) processing
• Uses any type of temperature sensor.
• External compensation for accuracy, that is, no on-board temperature sensor.
• Results can be sent to any other AMC8/IOC8T card pairs in the same VM600 rack.

Discrete signal interface (DSI) inputs
Control signal
• Alarm reset (AR) : A closed contact between the DSI AR and RET inputs resets the alarms latched by the card pair
• Danger bypass (DB) : A closed contact between the DSI DB and RET inputs inhibits (bypasses) the danger relay outputs
Operating principle : Detection of an open circuit or a closed circuit on the input
