ES2117

Key Features:

• Fully isolated between all circuits: Inputs, outputs, alarm, network ports, enclosure, and power are isolated from each other for safety and noise immunity.
• High-density stackable unit: Stacked mounting puts a lot of I/O in a very small footprint to save panel space.
• Modbus TCP/IP or UDP/IP protocol: I/O functions as slave to host controller.
• Peer-to-peer i2o communication: Inputs to one unit automatically actuate outputs on another over Ethernet link.
• Channel-to channel input isolation: Inputs provide high or low-side sensing for AC or DC circuits.
• Automatic change of state detection: Inputs detect quick momentary changes of state that occur between polling.
• Logic inversion (i2o only): Active high inputs can switch remote peer-to-peer outputs on or off.
• Change-of-state or timed updates: Event-driven updates transmit data in less than 10ms between peers with i2o.
• 10 Modbus TCP/IP sockets/sessions: Multiple masters can talk to an EtherStax unit at the same time.
• Local alarm function: Dedicated failsafe relay is controlled via watchdog timer and link-loss conditions.
• Heavy-duty 2A relays: 16 SPST outputs provide high/low-side 2A switching up to 250V AC or 110V DC.
• Programmable outputs: Normally open relays are configurable to energize or de-energize on power-up.
• Built-in slave relays: Inputs can control outputs on same unit to provide slave relay interface.
• Self-test checks I/O operation: Unit checks internal I/O communication and allows verification via web browser.
• Watchdog timers: Communication fault sends output to a pre-defined state or holds the last value.
• Operating Temperature: -40° to +65°C.
