2.8: Nexus External I/O Modules (Optional)
The following multiple analog or digital I/O modules mount externally to the Nexus 1250/1252 Monitor.
The Nexus 1250/1252 Monitor supports up to four I/O modules using internal power. Use the additional
power supply, EIG PSIO, to extend I/O capability. See section 3.4 for mounting diagrams. See Chapter
9 for details on installation and usage of the Nexus External I/O Modules.
Q Analog Transducer Signal Outputs (Up to two modules can be used with the Nexus 1250/1252.)
• 1mAON4: 4 Analog Outputs, self powered, scalable, bidirectional.
• 1mAON8: 8 Analog Outputs, self powered, scalable, bidirectional.
• 20mAON4: 4 Analog Outputs, self powered, scalable.
• 20mAON8: 8 Analog Outputs, self powered, scalable.
Q Analog Transducer Inputs (Multiple modules can be used.)
• 8AI1: 8 Analog Inputs 0–1mA, scalable and bidirectional.
• 8AI2: 8 Analog Inputs 0–20mA, scalable.
• 8AI3: 8 Analog Inputs 0–5V DC.
• 8AI4: 8 Analog Inputs 0–10V DC.
Q Digital Dry Contact Relay Outputs (Multiple modules can be used.)
• 4RO1: 4 Relay Outputs 10 Amps, 125V AC, 30V DC, Form C.
Q Digital Solid State Pulse Outputs (Multiple modules can be used.)
• 4PO1: 4 Solid State Pulse Outputs, Form A KYZ pulses.
Q Digital Inputs (Multiple modules can be used.)
• 8DI1: 8 Digital status inputs Wet/Dry Auto Detect, up to 300V AC/DC.
Q Other I/O Accessories
• PSIO: Additional power supply for up to six I/O modules. This unit is necessary if you are
connecting more than four I/O modules to a Nexus 1250/1252 Monitor.
• MBIO: Bracket for surface-mounting I/O modules to any enclosure.
