DESCRIPTION
The MM4001 modules are used to provide an output voltage or current proportional to an RTD input signal. It is useful in measuring temperatures with a variety of RTD materials. OPTIONS The following options are available on the MM4001 & MM4001ISO: U All circuit boards conformal coated for protection against moisture. DC Power Inverter-isolated 12 V or 24 V DC power. The module utilizes a single constantcurrent source to excite the RTD and also has an accurate and stable leadwire CONTROLS compensation circuit for compensating Two controls, ZERO and SPAN, are 3-wire RTDs against leadwire effects. accessible from the top of the module. CASE DIMENSIONS INCHES [mm] 1 2 SPECIFICATIONS RTD Input 3-wire or 2-wire, 10 ohms to 2000 ohms Input Range select any range within RTD limit [min span 25°F/14°C (100°F/55°C with 10 ohms RTD)] Excitation Current 10 ohms 10 mA 100 ohms 5 mA 1000 ohms 0.5 mA 2000 ohms 0.2 mA Output Range Voltage select any range from -10 V to +15 V, 10 mA max load...
