The MAQ20-FREQ is an 8-channel frequency input module designed to measure signals from 1 Hz to 1 MHz with 50 mV sensitivity, suitable for magnetic pickups, contact closures, and TTL inputs. Each channel features 1500Vrms input-to-bus isolation and 240Vrms continuous overload protection. Four configurable 5V excitation outputs are available for sensor powering or logic interfaces. The module supports individual channel configuration for range and alarms, selective channel scanning, and operates within a -40°C to +85°C temperature range. It is housed in a 4.51" x 0.60" x 3.26" enclosure with a pluggable terminal block and meets Heavy Industrial CE, UL/cUL Class I Div 2 Groups A-D (File E232858), and RoHS III standards.
The MAQ20 frequency input module offers 8 input channels for measuring frequencies up to 1MHz. All channels are individually configurable for range and alarms to match the most demanding applications. Four controllable outputs can be used for sensor excitation or as 5V logic compatible outputs. High, Low, High-High and Low-Low alarms provide essential monitoring and warning functions to ensure optimum process flow and fail-safe applications. Field I/O connections are made through a pluggable terminal block with positions designated for the termination of wiring shields.
Input-to-bus isolation is a robust 1500Vrms and each individual channel is protected up to 240Vrms continuous.
Channels in a module can be selectively enabled for scanning. All channels are enabled by default; however, non-used channels can be disabled to increase the system sampling rate of enabled channels.
