Data acquisition and control system modules for industrial applications
Dataforth’s MAQ-DIV20/MAQ-DIVC20 and the MAQ20-DODC20SK data acquisition and control system modules are part of the MAQ20 series and are designed for a wide range of industrial applications.
The MAQ20-DIV20 and MAQ20-DIVC20 are two versions of the same module. The MAQ20-DIV20 module has 20 discrete input channels that interface to 10-132 Vac/Vdc signals. The MAQ20-DIVC20 module also has 20 discrete input channels, each with a 24 Vdc compliance voltage for interfacing to relay contacts, solid-state switches, or other devices that require an excitation. Field input connections on both modules are made through spring cage terminal blocks.
The MAQ20-DODC20SK has 20 isolated discrete output channels that can switch up to 60 Vdc signals and carry up to 3A of current. Channels can be switched individually or in blocks and have user configurable default output states, which are set upon power-up or module reset. Field input connections are made through spring cage terminal blocks.
Input-to-bus isolation is a robust 1500 Vrms in the MAQ20-DIV20/MAQ20-DIVC20 and MAQ20-DODC20SK modules, and each individual channel is protected up to 150 Vrms continuous overload in the case of wiring faults or inadvertent wiring errors. In addition, the MAQ20-DODC20SK has 150 Vrms channel-to-channel isolation. Overloaded channels do not adversely affect other channels in the module, thereby preserving data integrity.
Features include communications modules, analog input voltage, current, thermocouple, RTD and potentiometer, strain gage, and frequency modules. Other system advantages include:
- Industry’s lowest cost per channel
- ±0.035% accuracy
- Up to 240 Vrms continuous field input/output (I/O) protection
- ANSI/IEEE C37.90.1 transient protection
- Dedicated graphical control software packages
- Advanced features including integral PID control, alarms counters, timers, and pulse width modulations (PWMs)
- 7 to 34 Vdc input power
- -40 to 85°C (-40 to 185°F) industrial operating temperature.
