Physical and Environmental Characteristics
It features a robust extruded aluminum housing, suitable for G3 class (severe) environments as defined by ISA standard S71.04. The operating temperature range is -20 to +70°C (-4 to +158°F), and the storage temperature range is -40 to +70°C (-40 to +158°F). The relative humidity range is 5% to 95% (non-condensing). The altitude range is -300 to +3,000 m (-1,000 to +10,000 ft) for operation and -300 to +12,000 m (-1,000 to +40,000 ft) for storage.
Installation and Maintenance
RH916CA: Suitable for 32-channel, 30V DC voltage monitor inputs, with logic zero being 0 - 5V DC and logic one being 15 - 30V DC. It is a passive feedthrough type with FBM217 group isolation. It is often used in low-voltage signal monitoring scenarios, such as monitoring low-voltage status signals of field devices.
RH916XZ: Supports 32-channel, 24V DC contact sense inputs, with contact wetting provided by the FBM. It is also a passive feedthrough type with FBM217 group isolation. It is widely used in systems that need to detect device contact status and use 24V DC power supply.
RH916YA: Designed for 32-channel voltage monitor inputs with a maximum voltage of 132V AC or 150V DC. It has clear voltage ranges for logic states, and the input current is limited to a maximum value when in logic one. Channel isolation is provided by the termination assembly. It is suitable for occasions where monitoring relatively high AC or DC voltage signals is required.
RH916YB: Used for 32-channel contact sense inputs with a maximum voltage of 132V AC or 150V DC, with external excitation. It has corresponding logic voltage ranges and input current limits, and provides group isolation. It is often used in device contact detection under high voltage.
RH916QA: Suitable for 32-channel, 240V AC contact sense inputs with external excitation. It specifies the voltage ranges for logic zero and logic one, as well as the maximum input current, and has group isolation. It is used in high-voltage AC contact detection scenarios.
