Softstart UK has introduced a new range of high performance micro PLCs, offering high speed, stable and highly reliable control across a whole spread of industrial automation applications. Manufactured by Delta Electronics, these second generation DVP series controllers offer increased program capacity and data register size, along with high execution speeds, impressive in-built functionality and flexible expandability, setting these micro PLCs apart from competing designs.
Flexible expandability comes in the form of two types of expansion modules: high speed modules that mount on the left hand side of the CPU, and standard modules that mount on the right hand side of the CPU.
combine fast operation, numerous instructions and multiple function cards with support for all leading communications protocols.
Kicking off the range is the DVP-SS2 – a slim, economic PLC offering eight inputs, 6 outputs as standard, with a choice of relay or NPN transistor outputs. The PLC can be expanded to a maximum of 480 I/O, giving it plenty of scope to tackle even quite sophisticated machine control operations. Built-in motion control functionality includes four sets of 10kHz pulse outputs and eight sets of high-speed counters.
A step up in sophistication is the DVP-SA2 – a slim, advanced PLC offering eight inputs and four outputs, with a choice of relay or NPN transistor outputs, and advanced motion control capability. The motion functionality includes four sets of high-speed pulse outputs, eight sets of high speed pulse inputs and support for two-axis linear and arc interpolation.
The DVP-SE is a network type advanced slim PLC providing eight inputs and four outputs, with a choice of relay of NPN transistor outputs. Designed as the most comprehensive network type slim PLC in the industry, it provides built-in Ethernet support for both MODBUS TCP and EtherNet/IP, and includes an IP Filter – a firewall function that offers a first line of defence and protection from malware and network threats. Completing its standard interface options is built-in USB connectivity. The DVP-SE can accommodate both left side high speed and right side standard expansion modules.
The DVP-SX2 is a slim, analogue I/O PLC providing four analogue inputs and two analogue outputs in addition to eight digital inputs and four outputs, which can be either relay, NPN or PNP transistor outputs. The analogue I/O offers 12-bit resolution, and can be 0-20mA, 4-20mA or -10V to +10V. The PLC provides high performance PID auto tuning functionality and impressive motion control functionality, including four sets of high pulse outputs, eight sets of high speed pulse inputs, and support for 2-axis linear and arc interpolation. Completing its standard interface options is built-in USB connectivity. The DVP-SX2 can accommodate both high speed and standard expansion modules.
Top of the range is the DVP-SV2 – a functional slim PLC providing larger program capacities and data registers for more demanding and complex applications. Excelling in motion control tasks, the DVP-SV2 includes up to four high-speed (200kHz) pulse outputs and supports a maximum of four hardware 200kHz high-speed counters. It offers numerous motion control instructions to meet applications that require high-speed and high-precision positioning control, such as labelling machines, packaging machines and printing machines. The DVP-SV2 also offers linear and arc interpolation motion control, and provides up to 16 external interrupt pointers. With 16 inputs and 12 outputs as standard, offering a choice of relay or NPN transistor outputs, the DVP-SV2 offers enough functionality out of the box to tackle even the most demanding machine control applications, but can also accommodate both left side and right side expansion modules, including Ethernet communications.
All models in the second generation DVP range also include RS232 and RS485 ports, with support for standard MODBUS and PLC Link function.
A host of expansion modules are available to provide increased flexibility. High speed extension modules mount on the left hand side of the CPU, and include network connectivity (DeviceNet master, CANopen master, Ethernet, Profibus slave, RS485/422 and BACnet slave), analogue I/O, and a load cell/tension control module. There is also a range of general extension modules that mount on the right hand side of the CPU. These include modules for communications (Profibus slave and DeviceNet slave), temperature measurement and motion control for single axis positioning, along with analogue and digital I/O modules.
