Enerpac® receive unit, SLR1 series, for use with: SafeLink wireless communication, specifications: 2.4 GHz radio frequency, 21 dbm conducted transmit power, 10 to 30 VDC input machine control/24 VDC NMOS sinking output power, modbus RTU RS485/ethernet IP/modbus TCP/IP receiver communication protocols, 2.23 in W.
Features
- Safe
- Link receive units can supply the outputs by using the standard modbus RTU RS-485 protocol, this output uses the five pin connector on the receive unit, if ethernet protocol is preferred, an ethernet bridge is available to convert the modbus RTU R-485 to ethernet IP or modbus TCP/IP
- Link provides wireless communication between the fixture mounted send unit and the machine control interfaced receive unit
- A pressure switch is used on the fixture to monitor the circuit pressure, if the pressure switch on the fixture goes open, the receive unit communicates the changed status to the machine control through either 24 VDC, modbus RTU RS-485 or ethernet IP protocol or modbus TCP/IP
- The machine control would interrupt the machining process, the send unit can also be used with limit switch based position sensing clamps to verify clamped or unclamped status for robotically loaded systems
- Link can provide a discrete 24 VDC output signal for systems of up to four fixtures, each send unit can provide up to three outputs to the receive unit, the receive unit has six terminal stations, which are assigned to send units in groups of three, so each receive unit can be paired with two send units when using the 24 VDC output, for extra capacity an expansion module provides an additional terminal strip, adding two more sets of three terminal stations
- Fixture mounted "send" unit uses radio communication to monitor pressure and/or clamp position
- 2.4 GHz frequency band for global acceptance
- "Frequency hopping" used to for signal stability, even in busy production environments
- "Send" units are easily reassigned to a different "receive" unit so fixtures can be moved between machines
- No limit to the number of systems used in a production area
- "Send" units are internally powered by a replaceable 3.6 VDC lithium battery - provides up to 3 year battery life
- "Send" units are sealed to IP67 for protection from contamination and coolant
- LED lights for visual status indication
- LCD display window for setup and status display
