Wireless 4-ch Voltage Input, 2-channel Voltage Output,
2-channel Digital Input and 2-channel Digital Output Module
The ZT-2026 is a wireless ZigBee module that offers 4 differential analog input channels(Current input requires optional external 125 Ω resistor), 2 analog output channels, 2 digital input channels and 2 digital output channels and provides a programmable analog input and output range. Each analog input channel can be configured to an individual range and each has 240 Vrms overvoltage protection. There are also options for a power-on value and a safe value. Users can easily configure the module address, protocol, checksum, ZT-PID, ZT-channel and type code settings using a combination of rotary and DIP switches.
